Abstract

A portable computer has incorporated therein a central processing unit, a display apparatus and a timer circuit. This portable computer is also provided with exclusive operation keys, wherein image data corresponding to a predetermined condition can be displayed on the display apparatus only by depressing the predetermined exclusive operation key and schedule data judged from a date of present time point can also be displayed on the display apparatus only be depressing the predetermined exclusive operation key.

Claims

1. An electronic organizer, comprising:

computer control means for controlling and organizing data, the data being organized as pages in a book;

input means coupled to the computer control means for entering data into the electronic organizer;

memory means coupled to the computer control means for storing said data;

display means coupled to the control means and the memory means for displaying at least one page of data; and

an exclusively dedicated operating key operatively coupled to the computer control means for placing and removing at least one electronic bookmark on a page of data so that the page of data so marked can be immediately accessed by actuation of said key.

2. An electronic organizer, comprising:

computer control means for controlling and organizing data, the data being organized as pages in a book;

input means coupled to the computer control means for entering data into the electronic organizer;

memory means coupled to the computer control means for storing said data;

display means coupled to the control means and the memory means for displaying at least one page of data; and

an exclusively dedicated operating key operatively coupled to the computer control means for placing and removing at least one electronic bookmark on a page of data so that the page of data so marked can be immediately accessed by actuation of said key, the bookmark comprising a memory within which is stored a logic address corresponding to a memory address at which said page of data is stored.

3. An electronic organizer, comprising:

computer control means for controlling and organizing schedule data, the schedule data being chronologically data organized as pages in a diary;

an exclusively dedicated operating key operatively coupled to the control means and the timer means for causing display of schedule data having a data associated therewith matching the internal date data generated by the timer means.

4. A method of controlling an electronic organizer which controls and organizes data, the data being organized as pages in a book, comprising the steps of:

actuating an exclusively dedicated operating key;

generating a logic address;

accessing a memory location determined by said logic address;

retrieving a page of data corresponding to said logic address from said memory; and

displaying an image corresponding to said page of data.

5. A method of controlling an electronic organizer which controls and organizes schedule data, the data being organized as pages in a diary and stored in a memory, comprising the steps of:

actuating an exclusively dedicated operating key;

detecting actuation of the exclusively dedicated operating key;

generating date data with a timer means;

generating a logic address based on the date data if the extensively dedicated key was actuated; and

retrieving schedule data associated with a date matching the date data.
